It depends upon the fastidiousness of the controller. If any insist on a valid ICAO code them you put ZZZZ and in the Remarks column of the flight plan write: DEST/ROURKE'S DRIFT or whatever. The X codes I use for the UK Airfield database are non standard and technically don't get used in any real aviation activity. bones -----Original Message----- From: jhb-bounce@xxxxxxxxxxxxx [mailto:jhb-bounce@xxxxxxxxxxxxx] On Behalf Of FrankTurley@xxxxxxx Sent: 01 September 2007 15:51 To: jhb@xxxxxxxxxxxxx Subject: [jhb] Unknown Airfields in IVAO While doing the farm strips I have checked in on the Eye, it reports Gerry's references as per my flight plan ICAO entries but it names them as unknown. Does this cause any sort of problem for the controllers, or do they just ignore VFR flights anyway? Frank T.
